Operating Instructions

Infrared Remote Control for EC2

The EC2 series of electronic controls can be easily and quickly programmed by means of the remote control unit using single keypad operations.

Until now, in fact, programming the multi-function instruments dedicated to the refrigeration sector was a very complex procedure. This is why EMERSON has enhanced the EC2 series with the remote control unit, which may be used not only to program the controller from a remote position but also to allows the user to set the main working parameters easily and fast. Today, modifying any parameter of an EC2 unit is as easy as controlling the volume of your TV. An interesting feature of the EC2 series is the possibility of selecting the access code (H3) of each controller so as to further simplify the use of the remote control unit. In fact, if your control panel includes several controllers, selecting a specific access code will allow you to modify only the parameters of the unit the code refers to, without interfering with the other controllers.

Changing the value of a parameter requires a special procedure (see 'ENABLE' button). Further safety is also provided by the 'H2' parameter that allows you to protect your system from unwilling or unauthorised access or modification of all set data.

REMOTE CONTROL UNIT: KEYPAD

On the basis of the function performed, the buttons on the remote control unit have been grouped as follows:

•Buttons to activate / deactivate the use of the remote control unit

•Pre-programmed buttons for the modification of the values of the main parameters

•Buttons for the remote control of the EC2 keypad

BUTTONS USED TO ACTIVATE/DEACTIVATE THE USE OF THE REMOTE CONTROL UNIT

The buttons shown on the left are the remote control unit ON/OFF buttons. They also allow you to memorize any new parameter value.

Note: A red LED indicator will be displayed on the front panel of the controller to acknowledge that a signal is being received from the IR handset.

ENABLE (blue zone)	enables the use of the remote control unit;
PRG (blue zone)	1) ends	the programming procedure	and
	memorizes the new values given to the
	parameters;
	2) silences the buzzer when programming the IR
	controller	via remote control unit;
ESC (orange zone)	interrupts the transmission without memorizing the
	modifications;
0 … 9 BUTTONS:	allow you to select the access code. We advise
	you to give each controller a specific access code,
	especially when your control panel includes
	several IR instruments or when all of them		are
	exposed to the beam of the remote control unit. In

this way you will be able to modify exactly the parameters you want to change, without interfering with the data of the other controllers.

(See also 'How to use the remote control unit' and 'How to select the password').

BUTTONS USED TO MODIFY THE MAIN PARAMETERS (DIRECTLY ACCESSIBLE BUTTONS)

The most frequent parameters are directly indicated on the remote control unit. They are grouped in three zones:

• temperature parameters (grey zone);

• defrost parameters (white zone);

• superheat parameters (grey zone).

For the correct use of the buttons see 'How to use the remote control unit' next page.

BUTTONS FOR THE REMOTE CONTROL OF

THE EC2 CONTROLLER

The green zone of the remote control unit reproduces exactly the keypad of the EC2 instruments and allows you to perform the same operations, as if you were directly acting on the keypad.

Here are the main functions of the buttons:

SEL displays the value of the selected parameter

1) goes to the next parameter

2)increases the displayed data (parameters selection phase)

Service

Service (grey) sends the Neuron ID

1) goes to the previous parameter

2)decreases the displayed value (parameters selection phase)

For the correct use of the buttons see 'How to use the remote control unit' next page.
